Common John Deere 3046r Problems and Troubleshooting Tips

John Deere is recognized for altering vendors repeatedly. That implies that its pieces are hastily outdated. At times, service is hard to obtain for John Deere models that are not even that outdated. Even though you are purchasing your tractor, new or used, the ultimate conclusion is going to boil down to unique, distinct variables. 

Primarily, you’ll need to locate a dealership you have good feelings about. You’ll also need to examine different tractor brands to discover the model that is a proper fit for your specific needs.

Below is a report documented by a John deere 3046r tractor user.

At 6 months old, the three-point hitch quit working (wouldn’t drop even with ballast box attached). Valves, etc., have been replaced numerous times but still won’t work. John Deere finally agreed to completely dismantle the back end and check every component.

I am trading this junk off and am going to let the dealer put up with this nonsense. Almost a year is too long for not being able to fully use a new unit and today, the control for my 4-in-1 bucket stopped working.

The air conditioner worked very poorly and needed new controls as well.”

These problems can be genuinely annoying and worsen when you don’t see anyone help you with them. But not to worry.

Let’s briefly look through the various troubleshooting tips.
